First I want to start to introduce myself. I am John, I live in The Netherlands, and I have a small business in repairing and restoring watches.
I am specialised in Seiko divers. These movement are sturdy, cheap, and nice to work on. I have a big stock of spare parts, and after market parts are available. After Christians call for some contribution to his log, I saw an oppurtunity to share my projects to a bigger audience. So I wil post here some of my mods and restorations. I hope you’ll enjoy them as much as I enjoy Christians log.
The Seiko 6309-704* is a very popular model under collectors. It has a distinctive case shape, known as “Turtle” or “Cushion”.
The best ones are the ones with original dial and hands, but often they come in a very bad state, beyond salvation.
Fortunately there are after market parts for them available, so its possible to resurrect them. Its a pain in the neck for the fanatic collectors, but I think a refurbished watch is better than no watch.
